First record of <i>Pluteus chrysophaeus</i> and reexamination of <i>Pluteus leoninus</i> from Japan

Abstract

First record of Pluteus chrysophaeus and reexamination of Pluteus leoninus from Japan P. chrysophaeus. Therefore, we redescribed and illustrated P. leoninus based on the new Japanese material.The specimens examined in this study are deposited in the herbaria of the Hokkaido University Museum (SAPA) and the National Museum of Nature and Science (TNS). Macroscopic characters were described by observations on dried or fresh materials. For light microscopic observations, sections of dried specimens were mounted in water, 3% or 5% (w/v) KOH, and phloxine B solution on glass slides. Thirty randomly selected basidiospores were measured under a light microscope at 1000× magnifi cation. Length measurements excluded the apiculus for basidiospores. The abbreviation Q is the ratio of length to width of basidiospores.
